VEHICLE FOR TRAVERSE ON A MONORAIL SYSTEM Filed April 28, 1955 UVVE/VT'OR WML/AM Maw United States Patent VEHICLE FOR TRAVERSE SYSTEM William Muir Robb, West Drayton, England, assignor of one-half to Road Machines (Drayton) Limited, West Drayton, England, a British company Application April 28, 1953, Serial No. 351,565 7 Claims. (Cl. 105-156) ON A MON ORAlL gagement with the rail.

The object of the present invention is to provide means whereby the vehicle is tilted inwardly relative to a curve in the track so as to improve the cornering characteristics of the vehicle.

Fig. 1 is a side elevation of the vehicle which is illustrated engaged upon a part of a monorail track.

Fig. 2 is an enlarged plan of one end of the frame of the vehicle illustrating the manner of mounting a bogie unit Within the frame.

Fig. 3 is a part section on the line 33 of Fig. 2 and Fig. 4 is an end elevation of a bogie unit showing its engagement with the frame of the vehicle which is shown in section.

The body of the vehicle is shown diagrammatically at 5 and can desirably be side tipping.

my co-pending patent application No. 28, 1953.

2,731,922 Patented Jan. 24, 1956 longitudinal axis of the vehicle are of a diameter such as to substantially fill the distance between the walls of the inward direction relative to the curve.

Depending from the circular frame 10 on opposite sides of the rail 9 The right hand bogie unit, as viewed in mounted thereon a self-contained motor and gear box for driving the track wheel 8, this mechanism being diagrammatically illustrated and designated by the reference 20.

I claim:

1. A vehicle for traverse on a monorail system Wherein a pair of bogie units are turnable in a vehicle frame Fig. 1, has

vehicle frame, said track sections having inclines extending upwardly toward the mid part of said vehicle frame to effect a positive tilting of the vehicle relative to the bogie units when the track wheels of the bogie units are turned out of alignment with the longitudinal axis of the vehicle.

2. A vehicle for traverse on a monorail system, said vehicle including a vehicle frame, a pair of wheeled bogie units each having a circular track of channel section, the channels of which open outwardly, two pairs of rollers surfaces; the rollers of each said additional pair extending into the channel of one oftsaid circular tracks and engaging the inclined surfaces of said wedge blocks, thus serving to control the extent of tilting said' vehicle frame.

3. A vehicle for traverse on a monorail system, said vehicle including a vehicle frame, a pair of wheeled bogie units each having a circular track of channel section, the channels of which open outwardly, two pairs of rollers carried by said vehicle frame and having the axes aligned with an axis about which the vehicle frame is tiltable, the rollers of each pair lying within the channel of one of said circular tracks, and two additional pairs of rollers carried by said vehicle frame, the rollers of each said additional pair being mounted on axes transverse to the axes of the first mentioned rollers, the rollers of each said additional pair extending into the channel of one of said circular tracks and serving to control the extent of tilting said vehicle frame, wedge blocks fixed within the channels of said circular tracks, the wedge blocks within each channel having oppositely inclined surfaces the rollers of each of said additional pairs engaging the inclined surfaces said wedge blocks and cooperating therewith to tilt said vehicle frame.

4. A vehicle for traverse on a monorail system wherein a pair of bogie units are turnable in a vehicle frame, each of said bogie units having a section of track extending fore and aft on each side thereof, a roller engaging each such track section, said rollers being carried by said vehicle frame, said track sections having inclines extending upwardly toward the mid part of said vehicle frame to effect a positive tilting of the vehicle relative to the bogie units when the track wheels of the bogie units are turned out of alignment with the longitudinal axis of the vehicle, each bogie unit being provided with a pair of rollers for engagement on opposite sides of a rail of such monorail system.

5. A vehicle for traverse on a monorail system wherein a pair of bogie units are turnable in a vehicle frame, each of said bogie units having a section of track extending fore and aft on each side thereof, a roller engaging each such track section, said rollers being carried by said vehicle frame, said track sections having inclines extending upwardly toward the mid part of said vehicle frame to effect a positive tilting of the vehicle relative to the bogie units when the track wheels of the bogie units are turned out of alignment with the longitudinal axis of the vehicle, each bogie unit being provided with a pair of rollers for engagement on opposite sides of a rail of such monorail system, each bogie unit having a flanged wheel rollable along such rail, the last mentioned rollers being located respectively ahead of the leading flanged wheel and behind the trailing flanged wheel.

6. A vehicle for traverse on a monorail system wherein a pair of bogie units are turnable in a vehicle frame, each of said bogie units having a section of track extending fore and aft on each side thereof, a roller engaging each such track section, said rollers being carried by said vehicle frame, said track sections having inclines extending upwardly toward the mid part of said vehicle frame to effect a positive tilting of the vehicle relative to the bogie units when the track wheels of the bogie units are turned out of alignment with the longitudinal axis of the vehicle, each bogie unit being provided with a pair of rollers for engagement on opposite sides of a rail of such monorail system, each bogie unit having a flanged wheel rollable along such rail, the last mentioned rollers being located respectively ahead of the leading flanged wheel and behind the trailing flanged wheel, each bogie unit being equipped with a pair of stabilizing rollers.

7. A vehicle for traverse on a monorail system wherein a pair of bogie units are turnable in a vehicle frame, each of said bogie units having a section of track extending fore and aft on each side thereof, a roller engaging each such track section, said rollers being carried by said vehicle frame, said track sections having inclines extending upwardly toward the mid part of said vehicle frame to effect a positive tilting of the vehicle relative to the bogie units when the track wheels of the bogie units are turned out of alignment with the longitudinal axis of the vehicle, each bogie unit being provided with a pair of rollers for engagement on opposite sides of a rail of such monorail system, each bogie unit having a flanged wheel rollable along such rail, the last mentioned rollers being located respectively head of the leading flanged wheel and behind the trailing flanged wheel, each bogie unit being equipped with a pair of stabilizing rollers, and resilient means for urging said stabilizing rollers into yieldable engagement with an element extending along such monorail system.
